“…Grafting carbon nanotubes on the surface of carbon fibers enables them to also exploit their remarkable properties in the field of fiber-reinforced polymer (FRP) composites, improving the bond at the fiber/matrix interface and enhancing the resistance to debonding during mechanical stress, even though with this procedure, the wettability of the fibers can be affected by the addition of high amounts of CNTs [ 32 ]. A proper functionalization of CNTs can still improve their dispersion in the epoxy matrix of the FRP, leading to a substantial growth of mechanical performance and impact resistance of the composite without impairing the wettability of the fibers [ 33 ].…”

“…The extraordinary chemical and physical properties of a wide variety of experimental nano-epoxies enable a wide range of applications, varying from coatings to structural adhesives, from FRP matrix to electrical/electronic components. Epoxy nanocomposites have found advantageous application in many industrial fields [ 59 , 120 ] such as aerospace [ 114 ], aircraft [ 119 ], automotive [ 33 , 110 ], buildings [ 18 , 67 , 145 , 146 ], electronic devices [ 17 , 86 , 99 , 128 ], sensors [ 90 , 110 , 115 , 127 , 144 ] (even for biomedical applications), anti-static materials [ 9 ], abrasive tools [ 103 ], anti-corrosive coatings (for example in marine environment [ 147 ] or pipes [ 10 ]), and structural applications [ 29 , 68 , 109 ] with self-sensing properties [ 127 ]. Often, the improved properties allow an efficient usage for multifunctional purposes [ 27 , 69 , 148 ].…”

This paper aims at reviewing the works published in the last five years (2016–2020) on polymer nanocomposites based on epoxy resins. The different nanofillers successfully added to epoxies to enhance some of their characteristics, in relation to the nature and the feature of each nanofiller, are illustrated. The organic–inorganic hybrid nanostructured epoxies are also introduced and their strong potential in many applications has been highlighted. The different methods and routes employed for the production of nanofilled/nanostructured epoxies are described. A discussion of the main properties and final performance, which comprise durability, of epoxy nanocomposites, depending on chemical nature, shape, and size of nanoparticles and on their distribution, is presented. It is also shown why an efficient uniform dispersion of the nanofillers in the epoxy matrix, along with strong interfacial interactions with the polymeric network, will guarantee the success of the application for which the nanocomposite is proposed. The mechanisms yielding to the improved properties in comparison to the neat polymer are illustrated. The most important applications in which these new materials can better exploit their uniqueness are finally presented, also evidencing the aspects that limit a wider diffusion.

“…However, few smooth surfaces appeared due to poor dispersion. At 0.4 wt.% of GA ( Figure 5G), GA started to distribute uniformly and the surfaces became absolutely rough due to GA incorporated on the surface of the membranes, what leads to increased viscosity of the solution leading to increased surface tension and fast solidification [44,45]. When GA concentration reached the peak ( Figure 5H), GA started to aggregate in the form of block particles which led to particle agglomeration owing to force interaction between GA particles.…”

Polyether block amide (PEBA) nanocomposite membranes, including Graphene (GA)/PEBA membranes are considered to be a promising emerging technology for removing CO2 from natural gas and biogas. However, poor dispersion of GA in the produced membranes at industrial scale still forms the main barrier to commercialize. Within this frame, this research aims to develop a new industrial approach to produce GA/PEBA granules that could be used as a feedstock material for mass production of GA/PEBA membranes. The developed approach consists of three sequential phases. The first stage was concentrated on production of GA/PEBA granules using extrusion process (at 170–210 °C, depending on GA concentration) in the presence of Paraffin Liquid (PL) as an adhesive layer (between GA and PEBA) and assisted melting of PEBA. The second phase was devoted to production of GA/PEBA membranes using a solution casting method. The last phase was focused on evaluation of CO2/CH4 selectivity of the fabricated membranes at low and high temperatures (25 and 55 °C) at a constant feeding pressure (2 bar) using a test rig built especially for that purpose. The granules and membranes were prepared with different concentrations of GA in the range 0.05 to 0.5 wt.% and constant amount of PL (2 wt.%). Also, the morphology, physical, chemical, thermal, and mechanical behaviors of the synthesized membranes were analyzed with the help of SEM, TEM, XRD, FTIR, TGA-DTG, and universal testing machine. The results showed that incorporation of GA with PEBA using the developed approach resulted in significant improvements in dispersion, thermal, and mechanical properties (higher elasticity increased by ~10%). Also, ideal CO2/CH4 selectivity was improved by 29% at 25 °C and 32% at 55 °C.

“…The curing of epoxy resins with apparent curing agents is carried out through addition polymerization or ion polymerization. [15][16][17][18][19][20][21][22][23][24][25][26] A latent initiator mixed with epoxy resin at room temperature can be stored for an extended period of time. When exposed to external stimulation, such as heating and photo-irradiation, the latent initiators initiate the curing reactions of epoxy resins.…”

Epoxy resin, which is extensively used in civil and industrial applications, shows excellent comprehensive performance, especially as a polymer matrix used in fiber-reinforced composites. A thermal latent initiator, used as an epoxy curing agent, has high storage stability and is widely applied in the preparation of epoxy-based blends and fiber-reinforced composites. In this review, the basic properties of epoxy resins and commonly used curing agents are discussed while progress on the synthesis of thermal latent initiators is reviewed in detail. Moreover, the curing mechanisms, thermal stability, and mechanical properties of epoxy resins with thermal latent initiators are also discussed.
